SOLE-SEWING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 545,484, dated September3, 1895. Application filed January 22, 1894. Serial No. 497,697 (Nomodel.)

To all whom. it may concern/.-

Be it known that I, Louis GoDDU, ot Winchester, county of Middlesex,State of- Massachusetts, have invented an Improvement in Sole-SewingMachines, of which the following description, in connection with theaccompanying drawings, is a specification, like letters and figures onthe drawings represent- I ing like parts.

ro This invention has for its object to provide a novel sole-sewingmachine a'daptedeither to stitch the upper to a sole for turned work ora welt and upper to a sole for welted work.

My improved machine contains a narrow work-rest, a curved awl, a curvedthread pusher or inserter, a thread-guide, and a thread-measuring hookto pull oft' from the tension device a quantity of thread for the nextstitch to be made, and a suitable feedzo ing device. In anotherapplication made by me, Serial No. 497,696, filed January 22, 1894, Ihave shown and described a machine for making a like stitch, the awl andthread pusher or inserter being, however, illustrated z5 as straight andas attached to carriers adapted to be slid in a guide-box movable atright angles to the direction of the feed of the material, the awl beingadapted to be thrust into the material and to be retracted,

3o leaving a hole for the thread, and then the said frame is tipped, asreferred to, to place the forked part of the thread pusher or inserterin line with the awlhole to meet the thread held distended between astationary thread-delivery and the hook of the measuring device.

In this my present invention I have mounted the carriers for the curvedawl and thread pusher or inserter side by side, so that theyI 4o may beoscillated about a common center of motion, the awl being actuated toenter the Work, after which it is retracted and the awl and threadpusher or inserter are moved .laterally, the feeding device holding thematerial until the thread pusher or inserter is put in position oppositethe awl-hole. In order, however, to make the stitch referred to andemploya curved awl and pusher side by side,

' I have been obliged to impart to the thread- 5o guide a slightmovement substantially at right angles to the direction of the length ofthe feed, a thread-measuring device engaging the thread at one side,co-operating with said thread-guide, stretching and laying the thread inthe path of movementof the thread pusher or inserter as it approachesthe awlhole.

One feature, therefore, of this present invention may be said to be asole-sewing machine includingthe following instrumentali- 6o ties: awork-rest, an awl-sector, an attached curved awl, a thread-pusher andthe sector carrying it, devices to move said sectors laterally in unisonand to rock them alternately,

a thread-guide, and a thread-measuring dev6 5 vice to draw the threadtherefrom and to move it into the path of the thread pusher or inserter,substantially as will be described.

Figure l vin front elevation represents al sufficient portion of asole-sewing machine 7o containing my present improvements to enablemyinvention to be understood. Fig. 2 is a right-hand end elevationthereof, the fast member of the clutch-pulley represented at the righthand in Fig. l being omitted. Fig. 3 is a sectional detail in the lineFig. l, looking to the right; Fig. 3a, a detail of the thread pull-off.Fig. 3b is a view showing the Work-rest and pitch-gage, together withthe pointed feeding device, engaging the sole and 8o part of thethread-insertar.

be described, which supports numerous parts. Fig. 6 is a detail of thethread-measuring de- 85 vice and the slide to which it is attached. Fig.7 is a detail showing the end of the th readguide and part of thework-rest, pitch-gage, and Welt-guide. Fig. 8 is a detail showing thethread-guide and its carrier detached; 9o Fig. 9, a detail of the leverfor moving the work-rest. Fig. 10 shows part of a turned shoe, and Fig.11 shows part of a Welt stitch ed to an upper/,and sole as it may be inthe machine herein to be described.

The column A, adapted in practice to rest upon the Hoon-has at itsupperendasuitable head A', which constitutes the rigid framework of themachine, parts lof the head serving as bearings for a main shaft A2,and-other roc parts to be hereinafter described. The main shaft has, asherein represented, at its righthand end, viewing Fig. 1, suitable fastand loose pulleys A3 A4 of the clutch variety under the control of amoving device or actuator A5, connected with a suitable treadle, (notshown,) so that the constantly-moving member A4 of the clutch may bemade to engage at suitable intervals the fast member A3 of the clutchand rotate the shaft when desired. Such devices are old and common inUnited States Patent No. 265,227, and need not therefore be hereinfurther described.

The main shaft a2 has fast upon it two hubs B C, the hub B having at itsperipherya camgroove b and a cam-face m15, (see Fig. 2,) and near itsedge a cam b', and at its inner side the hub B has a cam-groove b2. (SeeFig. 3.) The hub C has in its periphery a cam-groove c and a cam-facecx, and at its inner side an awl cam-groove c', (see Fig. 4,) and at itsouter lefthand side it has a second camgroove c2, the outline of whichis represented by dotted lines in Fig. 4.

The framework has suitableopenings cr hearings for the receptionof a rodor shaft D, upon which is clamped, by suitable setscrews d, (see Fig.5,) a movable hollow frame D', said set-screws entering threaded lugsof, as herein shown, a split sleeve or hub d', the said hub beingclamped firmly to said rod, the ends of the rod, as herein provided for,being therefore free to slide hack and forth in the bearings in theframe.

The frame D is of peculiar shape, and, as herein represented, it hasprojections d, one of which is broken off in Fig. 5, said projectionshaving suitable holes, as cl3, to receive a pin or stud d4, whichconstitutes the fulcrum on which is mounted the hub e of the awlsectore', (see Fig. 4,) to which is attached in suitable manner the awl e2.

The hub e of the awl-sector serves as a bearing for the hub fof thesector f', to which is secured the segmental thread pusher or inserterf2, adapted to act upon a measured thread and push it into a hole madeby the awl,.as will be hereinafter described. The awl-sector derives itsoscillating movement from a toothed sector-lever e3, mounted on a rode4, confined in suitable bearings of the head A by set-screws e5, thebearings being split so as to be pinched upon the rod, as bestrepresented in Fig. 2, the rear end of said lever e3 having a roller orother stud to enter the cam-groove c', before referred to. The sectorfderives its movement of oscillation from a toothed sector-leverjs,having also at its pivot the rod e4, said lever having a suitable rolleror other stud which enters the cam-groove b2 at the inner side of thecam B.

The movable frame D' has a roller or other studcl, which enters thecam-groove b at the periphery of the hub B, said cam-groovereciprocating said frame D laterally back and forth, as will bedescribed.

The framework has bearin g at As A9 on or forming apart of the head A',for a shaft A10, upon which is mounted to rock and slide lougitudinallythereon the feed-frame b3, having an arm b4, provided with a suitableroller or other stud b5, (see dotted lines, Fig. 4,) to enter thecam-groove c2 in cam C, to rock the frame on the shaft A10, said framehaving adjustably attached to it by screw b the feeder 117, having oneor more penetrating points b1?. The roll h5 is kept pressed into thegroove c2 by a spring 198, (see Fig. 1,) placed within a hollow part ofthe shaft A10, the outer end of said spring being acted upon by a screwb9', screwed into a threaded hub of the bearing A9.

vThe feeding-frame is provided with aroller or other stud 113, (shown infull and dotted lines, Fig. 4,) which enters the camgroove c at theperiphery of the hub C, said camgroove reciprocating the feeding-framelaterally.

The shaft A10, between the hubs of the feeding-frame, is shownasprovided with a slideblock blo, clamped on said shaft by a set-screwblz in ears of the splity hub of said block, flanges or feet of saidblock resting and sliding on tracks Z713 of the movable frame D', saidblock preventing any rocking movement of the said shaft. The block bloserves as a carrier for the thread-measuring device Z914, the shape ofwhich is best shown in Fig. G, it having near one end a hook 2, aset-screw 3 holding the threadmeasuring device in place. The block h1has a roller or other stud Z215, (see Figs. 3 and 6,) which is keptnormally against the cam b' bythe spring ha, before referred to, andsaid block and thread-measuring device have given to them a to-and-fromotion with relation to the thread-guide g.

The thread-guide g, shown as a hollow rod with a notched orbifurcatedendg', is at tached to a carrier g2, having a thread-passage 2Otherethrough, and shown as having a split hub g3 attached by screw g4(seeFig. 3) to a rocking stud g5, mounted in theframe D', the carrierbeing located in such manner with relation to the said frame as to beadjacent thereto throughout the length of the threadpassage 20, for apurpose to be described, the rear end of the carrier having a roller orother stud g, which is acted upon by the peripheral cam CX of thecam-hub C, (see Figs. l and 4,) a spring 10 (see Fig. 3) keeping theroll g against said cam, the latter causing the front end of thethreadguide to be raised and lowered, so as to put the thread issuingfrom said guide and held by the thread-measuring device in the path ofmovement of the thread pusher or inserter as it approaches the awlhole,the thread measuring device having drawn olf enough thread for the nextstitch and holding the said thread so that the said thread-pusher willmeet it at a point distant from the last stitch equal to the distance ofone awl-hole from another plus one-half the length of the loop of threadto be left in the awl-hole.

The thread t is taken from a suitable waxbox t', in which the wax isheated by steam IOC IIO

from a pipe t2, steam entering the frame D at p (see Fig. 4) fromasuitable source of supply, which may be a steam-chamber.

The pull-off consists of a lever h h2, pivotedat m5, and having (seeFigs. 3a and 4) a finger h3, on which is a roller h4. (See Fig. 5.) Thelever h has a roller or other stud h5, which also enters the cam-grooveb2. The thread is led from the stripper o, under the studs orthread-guides 4 5, as in Fig. 2, and over the roller h4 of the pull-0E,so that when the said roller is raised, as in Fig. 2, the pulloff drawsthread from the stripper and waxbox. The thread-tension devices-asuitable wheel or device about which the thread is given a turn on itsway into the thread-guideis prevented from rotating during theaction ofthe pull-off by the detent t4 in engagement with teeth t5, connected toa part of the tension device, the latter being carried by the frame D.)Vhen the pull-olf is moved, the pawl t4 prevents retrograde movement ofthe tension device s and causes to be pulled from the wax-box enoughthread for a new stitch, so that there is always left slack threadbrehind the tension device, so that the 4threadmeasuring device (ithaving engaged the thread) will, in drawingV the thread from thethread-guidahave only to overcome the friction of the tension device,which is usuallyT slight. The work-rest 'm consists of a narrow thinedge connected to an arm m', attached adjustably by a set-screw m2 to acarrier-bar m3, placed in guideways in the head A, so that it can slideonly longitudinally. The work-rest has, as shown, a pitch-gage m4,combined with it, which bears on the bottom of the sole while the upperor welt is pushed against the work-rest, that depending on whether aturned or a welted shoe is being stitched. I desire to hold thework-rest forward firmly while the stitch is being made and to relaxsuch pressure while the feed is acting to feed the shoe. To provide forthis, I have mounted on the frame D, at m5, a lever m6, provided with aroller-stud m7, which is normally kept against the peripheral cam m15 ofthe cam-hub B by a spring m8 (see Fig. 9) in a little tube at thelowerend of said lever, an adjusting-screw m9 being applied thereto tocontrol the force of the spring, the inner end of said spring entering apocket (shown by dotted lines, Fig. 3) connected to the frame D'.

The lever m6 has at its lower end teeth m10, which engage teeth m12 ofthe shank of the work-rest. (See Fig. 3.)

The arm ma of the work-rest, when a welt is to be attached, has securedto it by screws n a welt-guide n', which is of such shape andv depth asto let one edge of the welt come between the work-rest and upper whenthe latter contacts with a shoulder formed at the edge of the sole, asin the sectional detail', Fig. 1l.

Fig. lO shows part of a sole and upper adapted for a turn-shoe.

Having described the construction of the parts, Iwill now describe theoperation of the same. First assuming that the frame D is in itsposition farthest to the right, viewing Fig. 1; that the work-rest isway forward; that the feed device has been moved to the left, has actedto feed the material, and that it is yet down with its points in thematerial and acting to aid the operator in keeping the upper and' soleclamped closely together against the narrow work-rest; that thethread-guide g stands with its notched delivery end in its uppermostposition, and that the awl and thread pusher or inserter are both out ofthe material, now the thread-measuring device will be made to engage thethread of the lifted thread-guide, preparatory to pulling therefrom andthe tension device beyond it enough thread for the next stitch.

About as the measuring device engages the thread the thread-guide willbe lowered to remove the thread to be drawn out by the measuring devicefrom the path of the awl and the measuring device will be started topull off the thread, and as soon as the measuring device is out of theway of the awl the latter will be started forward to enter the work yetheld between the work-rest and the feeding device, and the measuringdevice will continue its movement to draw off thread and will completeits backward movement as or about as the awl retires from the work. Theawl having been retracted, the frame D will be moved to the leftsufficiently far to put the end of the thread pusher or inserter f2opposite the awlhole, the feed yet remaining stationary, and at the sametime the thread-guide and measuring device will move with the frame, butthe work-rest will not move. During this lateral movement of the frame Dto the left the thread-guide g will be lifted sufficiently to put thethread held between it and the thread measuring device across the holemade by the awl and in the line of movement of thethread pusher orinserter, so that as the latter is moved forward itwill engage thethread and put it into the awl-hole.

While the pusher is acting to put the thread into the awl-hole the thread-measuring device will be moved toward the thread-guide, suclrmovement being effected independently of the frameD by the spring bs,the threadguide then giving up to the pusher the thread held by itshook; but as soon as the thread pusher or inserter is lifted from thematerial the frame D is again started toward the right.

IOO

device is again started toward the left to again feed the material thework-rest will be pulled back slightly, so that while the feeding deviceis acting to feed the material the pressure between the material and theworkrest will be somewhat released; andthe feed having been effected,the work-rest will be again pushed forward, this happening, however,before the awl enters the work. The hollow frame D (see Fig. 4) receivessteam, as stated, at the inlet p, the steam following along a channel 6therein, (see dotted lines, Fig. 4,) at one side of said frame, thenceupwardly along a channel 7 below the top of the track 513, and back tothe rear end ofthe frame at its opposite side through a suitable channel8, (see dotted lines, Fig. 3,) and out at the outlet p2 into pipe t2,and thence in to the usual hollow casing surrounding the wax-box t', asbest shown in Fig. 2, whereby said frame is heated, the thread-carrierg2 being supported, as described, so that the heated portions of theframe are contiguous or adjacent thereto and heat it throughout theextent of the thread-passage 20.

l-Ieretofore while the opera-torwas removing a finished shoe andreplacing it by a shoe to be stitched a considerable portion of thethread was cooled by exposure to the air, and the operator had to drawoff and sever such cold portion before he could begin the stitching ofthe next shoe, the thread being drawn off until the heated portion wasbrought up to the stitch-forming devices.

By maintaining the thread heated throughout its length from the wax-boxto and particularly immediately adjacent to the stitchforming devices, Iobviate the waste occasioned by cutting off a portion of thread for eachshoe, and I increase the rapidity of operation of the machine, for thethread is always heated and ready for use at the stitchforming devices.
